This is a puzzle game we’ve had for around 12 years! One of the DC has got really into it but we can’t solve it. I remember a few years ago finding the solution on the internet but can’t for the love of God find it now.
It’s a plastic tray with Tetris like pieces, that you have to fit into the square tray in an alternating pattern of red and black on one side; and blue/black/yellow on the reverse.
DC has cracked the red and black as you see (photos) but the other side is driving us mad! Hellllppp!!
